Protection Monitoring
Complete Range Of DC And AC Protection Devices
Safety is paramount in solar photovoltaic systems. We have meticulously selected reliable devices that will protect yourself, your solar inverter and all the peripheral equipment (batteries and solar panels).
PV Combiner Boxes
These boxes are loaded with DC fuses, DC isolators and cable glands. They are used to protect multiple parallel strings in solar arrays. There are standard DIN rails for mounting fuse holders or terminals.
PV String Fuses And Holders
GAVE Electro DIN rail mounting fuse holders are made for Photovoltaic & DC applications. They are rated at 1000V and come in 12A, 15A and 20A. Terminals accept up to 10mm2 flexible cable or 16mm2 solid wire.
DC Isolators. Kraus & Naimer
The DC isolator is the safest means of manual isolation between PV arrays and inverters. It is suitable for all grid-tied and off-grid installations. The DC switch is installed close to the inverter. As a rule of thumb, the switch voltage rating is calculated if you multiply the 1.15 x Voc open circuit voltage of the string. The current rating is 1.25 x Isc the string Isc short circuit.
AC Isolator. Kraus & Naimer
All solar installations must have one of these switches. They provide the perfect means of manually isolating the solar inverter from the AC supply (Grid Voltage) or your AC loads if we are referring to an off-grid system. The right position for the AC isolator is next to the consumer unit.
